From 223,499 reviews, clients rate our iPhone Developers 4.9 out of 5 stars.We need a custom React Native native module or an integrated wrapper package that allows our application to upload photos, videos, and audio files from the user’s camera roll/local storage to a remote server. The absolute most critical requirement is robust, uninterrupted background uploading that survives app closure and system standby. Scope of Work & Requirements Cross-Platform Compatibility: Must work flawlessly on both iOS and Android. File Formats: Full support for images, large video files, and audio recordings. Background Resilience: Must leverage OS-native background tasks (like Background App Refresh configurations on iOS and WorkManager or foreground services on Android) to continue uploads when the app is minimized or closed. Chunked/Resumable Uploads: Support for mul...
I need a fully native media-export pipeline inside my existing React Native app for both iOS and Android. When the user taps the export button, the module should take the photos, videos, and audio tracks they have picked, decode them natively, composite the frames with smooth, dynamic transitions, run hardware-accelerated H.264 encoding, and finally hand back a ready-to-share MP4—either saved locally or sent straight to my upload API. Think of the workflow you might build with ffmpeg in the browser, but executed on-device with platform-specific performance and without round-tripping to a server. I’m expecting real-time or near real-time processing, clean audio sync, and minimal memory overhead. The solution must be exposed to JavaScript through a clean React Native bridge so...
My cross-platform AI-driven mobile app is suffering from performance issues that trace back to the data layer. On both iOS and Android, new records intermittently fail to save, and previously stored data sometimes disappears or reappears only after a forced refresh. This “database and saving” problem is the root cause of user-visible lag and occasional freezes when the app attempts to read or write. What I need: • Pinpoint why data is not saving correctly in the current database implementation and resolve it without breaking existing features. • Optimise the read/write cycle so that loading screens and UI interactions stay smooth even under poor network conditions. • Ensure fixes work consistently on the latest production versions of iOS and Android, then re...
I need a developer to extend my current product with a fully-functioning social media sharing feature. The goal is simple: allow users to share selected content straight to their preferred networks quickly and reliably, without disrupting the existing experience. Here’s what I expect: • A clean, intuitive share interface that fits the current UI • Support for the major platforms covered by each network’s latest API (Facebook, X/Twitter, Instagram, LinkedIn at minimum) • Proper handling of user permissions, callbacks, and error states • Lightweight code that will not slow page or screen loads • Clear hand-off documentation so I can maintain or expand the feature later Once built, I’ll test cross-platform functionality and review code quality. If ...
I need a single, consistent IPTV media-player application that I can install on Smart TVs, mobile devices and regular computers. The player must open both M3U playlists and Xtream-Code logins without any external converter, then organise the content into Live TV, series and movies automatically. Core functionality • Live TV playback with fast channel zapping • Full catch-up (time-shift) on channels that provide it • Integrated EPG grid and now/next info, refreshed from the playlist source • Category filtering and search across live, series and films • Simple remote-control navigation on TVs, plus touch gestures on phones/tablets • Reliable reconnection logic for unstable streams Target platforms – Smart TVs (Samsung Tizen and LG webOS are m...

I’m ready to turn my concept into a working software prototype that demonstrates a complete payments-processing flow through a finance API and then package that prototype as a beta mobile app for both iOS and Android. The build should cover the core screens, wire them to the chosen payments endpoints (Stripe, Plaid, or a similar REST-based service), manage tokenisation and callbacks, and surface basic transaction status inside the app. While payments processing is the immediate focus, I’d like the codebase structured so we can layer in other financial features later without major rework. I’m open to React Native, Flutter, Swift/Kotlin, or another cross-platform stack—whichever gets reliable TestFlight and Google Play Internal builds in the shortest time. Delivera...

I’m planning a new mobile application and I’d like a single developer to take it from concept to publication on both the App Store and Google Play. The core deliverable is a fully functioning app that runs smoothly on iOS and Android, complete with source code and any necessary backend integration. Because I don’t have a hard deadline, we can focus on clean architecture, thorough testing, and an intuitive user interface rather than rushing features. I’m open to discussing the tech stack you feel most comfortable with—whether that’s React Native, Flutter, Swift + Kotlin, or another modern framework—as long as maintenance and future scaling are straightforward. If you have a solid track record of building cross-platform apps, especially those that ...
I’ve got the full Xcode project and a complete set of screens for a social-media app that now needs to be compiled, code-signed, and shipped to the App Store. Your job is to take my existing Swift source, plug in the right certificates and provisioning profiles under my Apple Developer account, run a clean build, and walk the binary through App Store Connect until it is approved. The design files are final, so no UI work is required. What I need is someone comfortable with the usual iOS release pipeline—Xcode, TestFlight, App Store Connect metadata, screenshots, and, if Apple raises any flags, quick fixes or resubmissions. I will provide the source code, design assets, and access to my developer account as soon as we start. Deliverables • Signed IPA ready for TestFligh...
I’m getting ready to launch a new mobile adventure game and want a seasoned tester to run a full campaign play-through on both Android and iOS builds. Your strongest skill should be spotting performance issues and bugs: crashes, frame-rate drops, audio hitches, texture or UI glitches—anything that pulls the player out of the experience. While you play, please assess the difficulty curve, touch-control responsiveness, and overall menu clarity. I also value insight drawn from your background with adventure, strategy, and sports titles, so feel free to compare and contrast where relevant. Deliverables • Complete the story once on each platform, noting any platform-specific quirks. • Compile a reproducible issue log—steps, severity, and device details—ba...
I’m looking for end-to-end development of a mobile application for both Android and iOS, together with a fully integrated website. All three surfaces—Android, iOS and web—should draw from the same back-end so that a user who signs up or makes a change in one place sees it instantly everywhere else. Here’s what matters most to me: • One code-base per platform that feels truly native in speed and UX. I’m happy to use React Native, Flutter, Swift/Kotlin, or another modern stack you can justify. • A web front-end that mirrors the app’s functionality, built with a current framework such as React, , Vue, or an equivalent you prefer. • A clean, well-documented API layer (REST or GraphQL) that powers both the apps and the site, with secure au...

I’m ready to build a suite of polished Roku, Apple TV, and Fire TV channels and need a BrightScript specialist with multi-platform expertise who can take full advantage of Roku SceneGraph, RAF, and the latest SDKs. The CDN is already fully set up for all platforms, so you’ll focus on seamless channel architecture, UI/UX design, and integrating playback functionality. Here’s what I’m looking for: • Live streams will arrive exactly as they do on our Apple-TV-oriented feeds, so experience adapting HLS-style streams across platforms is essential. • Login is required. You should be comfortable wiring platform-specific authentication dialogs to a remote API and persisting secure tokens. • Demonstrable work with Roku, Apple TV, and Fire TV is critical; plea...

I need an Android application (APK only, no iOS for now) that can automatically accept incoming Rapido and Ola ride requests the moment they appear, then surface a simple confirmation screen to the rider. Core workflow • User opens the app and signs in with Firebase Authentication. New users must verify their phone number through an OTP flow. • From the home screen the driver can toggle Ola or Rapido acceptance on or off independently; when a service is switched off, no rides from that platform should be auto-accepted. • Whenever the toggle is on, the app stays in the foreground/background (your call on the best technical approach) and listens for ride offers. Matching offers must be auto-accepted in milliseconds, mimicking the speed of native Ola / Rapido acceptanc...

I already have my gameplay system fully designed on paper, the transition logic between states is clearly written, and I am now ready to translate it into Unity Visual Scripting. What I need is a short, focused tutoring session conducted in Arabic that shows, step-by-step, how to build the State Machine graph and wire it up to my existing C# MonoBehaviours. Your help will centre on mapping the transitions between the states I have defined, choosing the right variables to expose, and demonstrating the best practice for calling functions, reading values, and firing events from within the Visual Scripting graphs. Because the logic is already defined, the emphasis is on technique rather than design. Deliverables (all in Arabic): • Live call or screen-recorded walkthrough in the current ...

I want to build a complete society-management solution, very similar in spirit to MyGate or Society App, but tailored for our own residential community. The finished product must work seamlessly on iOS, Android, and the web from a single code-base or well-coordinated native stacks. Core functionality • Membership management: create, edit, suspend, or transfer memberships with role-based access for committee members. • Family & tenant profiles: every flat should hold owner details plus unlimited family or tenant records, each with their own login. • Payment gateway integration: monthly maintenance, utilities, and ad-hoc charges processed inside the app with automated invoices, receipts, and ledger exports. • Communication: real-time individual chat and group c...
I need help adding a bank-transfer payout option to my profile so I can start receiving client funds without delays. I already have an active account with GCB, so the task is to integrate that account, complete any required verification steps, and make sure withdrawals land smoothly in my bank. Here’s what I expect: • Clear guidance on the exact details the platform needs (routing codes, SWIFT/BIC, beneficiary info). • Step-by-step assistance completing the form or API link, including any identity or KYC checks. • A quick test or confirmation that the transfer method is live and ready for real client payments.

I have a single, large city-map scene that now needs to be split into four equally sized sections, each weighing in at roughly 20 MB once saved from Blender. Every section should keep medium-level detail so the skyline, streets, and key landmarks remain recognizable while still being light enough for mobile use. Once the segmentation is done, I’d like you to run a quick optimisation pass, bring the pieces into Xcode, and confirm that they compile, deploy, and render smoothly on an actual iPhone. I’m looking for practical feedback on frame-rate, memory footprint, and any import warnings so I can adjust the pipeline before we add interactivity. Deliverables • Four Blender files (or equivalent exported assets) around 20 MB each, preserving materials and basic city hierarchy...

I’m building a grocery-shopping mobile experience that will run exclusively on iOS. The scope for this first milestone is focused and clear: I need the shopping-cart flow and a seamless, secure checkout packaged in a Swift-based app that compiles cleanly in the latest Xcode. Beyond the usual polish expected on an Apple product, the cart must handle quantity updates, promo codes, tax and shipping calculations, and pass the final order to a payment gateway (Apple Pay support is strongly preferred). Smooth error handling and unit tests for the critical purchase path are important acceptance points for me. Deliverables • Swift/Xcode project with shopping-cart module • Checkout screen with payment integration • Brief setup doc and test report Once this core is soli...

I’ve built a fully-featured travel-planner and the front end is looking great, but before I press “submit” I want an experienced set of eyes on the back-end logic. Your job is to comb through the entire server-side code, isolate and resolve any functional bugs, optimize performance, and make sure every endpoint behaves exactly as it should under real-world load. Once the codebase is watertight, I’d like you to guide me through the final iOS App Store submission process—provisioning profiles, TestFlight builds, App Store Connect metadata and the actual push to review—so the release sails through Apple’s approval on the first try. You’ll have direct access to the repository and time with me to walk through existing architecture, run automated ...
I need an on-site check ofan address in Kuwait. Once I share the exact address, please visit the location, confirm the street details on-the-ground, and capture visual proof that the storefront appearance matches the address provided. During your visit: • Take 10–15 clear, GPS-tagged photos covering the full exterior, entrance, visible street number, and any distinguishing features. • Grab a live Google Maps screenshot on your phone that shows your current dot directly over the . Deliverables I expect: 1. A brief confirmation statement (correct / incorrect address) with any relevant notes. 2. The original GPS-embedded photos. 3. The Google Maps screenshot. No editing or compression, please—raw files only so I can verify the metadata. Let me know your avai...
I need a complete mobile shopping experience that runs smoothly on both iOS and Android. The application’s sole purpose is to sell physical products, so everything—from the first product photo a customer sees to the final “order placed” confirmation—has to feel fast, intuitive, and trustworthy. What matters most to me is a polished, fully-tested build that can be submitted to the App Store and Google Play without surprises. I will supply the product data and any brand assets you need; you’ll handle the rest of the build, including: • Designing an easy-to-navigate catalogue and cart flow • Implementing a secure checkout that supports the usual card and wallet options • Setting up the admin side so I can add, edit, or remove products a...
I’m developing Aitune, a mobile music-streaming experience where the ability to create, name, edit, and share dynamic playlists sits at the heart of the product. I already have a clear idea of the look and feel; what I need now is a developer (or team) who can turn that vision into a smooth, responsive iOS and Android application. The first release should focus on flawless streaming, fast search/browse, and—most importantly—robust playlist management. Users must be able to add or remove tracks on the fly, rearrange their order, and save unlimited playlists to the cloud so they sync across devices. While offline listening and social sharing are on the long-term roadmap, the current milestone is dedicated to getting playlist creation perfect. I’m open to React Nativ...
I need help getting over the hill with a website I own. Some of the buttons do not work and general ui. The database is good on netlify, the idea is to allow 25 free questions and then if you pay for access you get all questions for 1 month. I would like to have it as an app for both iOS and Android platforms. But I would also be happy with just a website that works and can be viewed on a phone. I am using , firebase for sign in and netlify for the data and was told I should use stripe for payments. let me know what you think. My max available budget is NZD 50 .oo Would you be able to do the work to achieve my vision at that price and with everything that is done already? thanks
I already hold roughly one million device tokens in an MS SQL database and need a reliable way to deliver two to three push notifications every day to the entire user base on both iOS and Android. Messages will vary between promotional offers, important updates and routine reminders, so the flow has to cope with mixed content and occasional spikes in send volume without dropping or duplicating tokens. Here is what I expect from the solution: • Direct integration with my existing MS SQL tables so the service can pull fresh tokens, mark successes or failures and record basic analytics. • Simultaneous support for Apple Push Notification Service (APNs) and Firebase Cloud Messaging (FCM) or any comparable gateway you recommend, with secure key management. • High-throughput...
I want to take a football (soccer) concept from sketch to launch on both Android and iOS, with realistic-style 3D graphics that still perform smoothly on low- to mid-range devices. The core of the experience is multiplayer: quick Bluetooth duels, LAN matches over local Wi-Fi, and full internet play with matchmaking and friend invites. Every mode should feel seamless and share the same user accounts so progress is never lost. Each player profile must track a Win/Loss record, unlockable achievement badges, and an elo-type ranking system. Add an in-game rewards loop—coins, cosmetics, or similar—that ties into these stats and keeps users coming back. Secure sign-in (Firebase, Game Center, or a comparable solution) is mandatory, as is localisation support so I can enable multiple c...
I need a single code-base mobile app—built in Flutter or React Native—that pairs over Bluetooth Low Energy with a white-label smart band using the manufacturer’s BLE SDK. I will provide the SDK libraries, UUIDs, and documentation as soon as we kick off. The goal is to compile and ship the same code to both iOS and Android stores. Core scope • Implement a smooth pairing/re-pairing flow. • Pull real-time metrics (steps, heart rate, battery level, etc.) and display them in simple dashboards. • Store data locally for offline access and render basic charts. • Support OTA firmware updates exposed by the SDK. • Produce signed .ipa and .aab builds ready for App Store and Google Play submission, along with clean, well-commented source code.

I’m looking for a skilled mobile developer who can create a streamlined Android app focused on business-operations efficiency, with inventory management as the core feature. What I need • A clean, intuitive Android application that lets my team add, edit, and track inventory in real time. • Secure user authentication so only approved staff can access or modify data. • Dashboard-style screens that show current stock levels, low-stock alerts, and simple analytics. • Ability to scan barcodes (camera-based) for quick item lookup and updates. • Cloud-based database or lightweight backend so everything stays in sync across multiple devices, even when a user switches phones. • Basic reporting export (CSV or PDF) for weekly inventory reviews.

I’m ready to bring a new 3D action-adventure game to life in Unity and need a developer who can guide the entire build for both PC and mobile releases. The core concept, visual style, and gameplay loop are already drafted; what I require now is a partner who can turn that vision into a polished, playable experience. Unity experience with 3D character controllers, physics-driven interactions, and cross-platform optimization will be essential. I’ll supply concept art, level sketches, and narrative beats—your role starts with prototyping, then iterating toward a feature-complete vertical slice, and finally preparing the full game for PC and mobile stores. Key deliverables: • Playable prototype demonstrating combat, exploration, and inventory basics • Optimised ...
I want a mobile application that lets contractors and residential clients manage building contracts from start to finish, all on their phones. The core of the app is a living contract: either side can propose changes mid-project, but nothing updates until both parties tap “accept”. Once approved, the amended clauses instantly recalculate and display the new running total so everyone stays in sync on scope and cost.
